    Abstract: A scanning probe microscope detects or induces changes in a probe-sample interaction. In imaging mode, the probe 54 is brought into a contact distance of the sample 12 and the strength of the interaction measured as the probe 54 and sample surface are scanned relative to each other. Image collection is rapidly performed by carrying out a relative translation of the sample 12 and probe 54 whilst one or other is oscillated at or near its resonant frequency. In a preferred embodiment the interaction is monitored by means of capacitance developed at an interface between a metallic probe and the sample. In lithographic mode, an atomic force microscope is adapted to write information to a sample surface.

    Abstract: A flow control device on a structure such that strain in the structure is at least partially transferred to the flow control device is disclosed having at least two states, or shapes, separated by an elastic instability region. The flow control device is arranged to rapidly transition, or snap through, from the first state to the second state when strain in the structure exceeds an activation threshold of the flow control device. A spoiler on an aerofoil has a rest position where it is substantially flush with the low pressure surface and an activated position where it protrudes from the low pressure surface and modifies the airflow over that surface. The spoiler bends to move from the rest position to the activated position when the strain in the aerofoil crosses a threshold. The deployed spoiler reduces the lift on the aerofoil, acting to reduce the lift induced strain of the aerofoil to which the spoiler is attached.

    Abstract: An optical device includes a first multi-mode waveguide, a first optical coupler coupled to the first multi-mode waveguide, the first coupler being tapered and curved, and a first single-mode waveguide having a first end coupled to the first optical coupler. The optical device may be used in an optical delay device. A method of propagating light in a first multi-mode waveguide toward a first optical coupler, propagating the light in the first optical coupler toward a first single-mode waveguide, the first optical coupler being tapered and curved, and propagating the light along the first single-mode waveguide is also disclosed.

    Abstract: A system (100) for subject (50) detection is disclosed. The system (100) comprises a plurality of radar systems (21, 31). Each radar system (21, 31) comprises an antenna configured to transmit an electromagnetic signal and to detect reflections of the electromagnetic signal and determine a plurality of data points corresponding with the position of reflectors. The system also comprises a processor (10) configured to receive the plurality of data points from each radar system (21. 31), and to process the data points to detect and/or track a subject (50) therefrom. Each of the radar systems (21, 31) has a boresight (22, 32), corresponding with an axis of maximum antenna gain for the electromagnetic signal. The plurality of radar systems (21, 31) comprises a first radar system (21) with a first boresight (22) and a second radar system (31) with a second boresight (32). The first boresight (22) is at an angle of at least 25 degrees to the second boresight (32).
